The scene where Eddie Murphy and Nick Nolte follow an informant into a subway station was filmed at the Church Street Station Muni subway stop in San Francisco. In the film, the station is constantly bustling with commuters, when in reality, it's one of the railway's least busy stops. It would be very difficult for anyone to "hide" in the crowd at this station, like Murphy and Nolte did. [Thanks to Patrick Fogerty]

The Railroad tracks crossing at Warnerville (SE of Oakdale) in Central Valley were used for the opening scenes.

I believe the bar "Torchy's", is the same bar used in a scene for "When A Stranger Calls"- at least the external shot. [Thanks to Chris Sweet]

The bar "Torchy's" is located at 218 and a half W. Fifth Street in Downtown Los Angeles CA 90012. The bar closed some time ago, but the original paneling behind the classic blinking "Torchy's" light still remains, and it now houses some new-age fashion store, and previously housed an electrical supplies store.[Thanks to Brian Doyle]

The gas station where Cates & Hammond clean up after their fight is an old Classic Texico station in Hollywood, on Highland a block or 2 south of Santa Monica Blvd.

When Cates leaves the police station to meet Reggie at VROMAN'S, the cadillac pulls out of the service alley/ ramp behind the Biltmore Hotel in downtown LA ( 5th & Grand ).That alley, as well as the hotel entrance has been used in countless films & TV shows(Buckaroo Banzai, Ghostbusters, Dave, The West Wing).

Also,San Francisco City Buses are electric, running off an overhead wire grid. There are a few shots of these in the movie, but in the bus chase/ shoot out they're magically gone. [Thanks to Matt Ullman]

Can you help? Do you know any of the San Fransisco, N. California (or any other) filming locations used for 48 HRS? [Please send them in]
